WEAR PLATE.

Application filed January 26, 1923. Serial No. 615,060.

To all whom it may concern Be it known that I, SIDNEY I). CAMPBELL, avcitizen of the United States, residing at San Antonio, in the county ofBexar and State'of Texas, have invented new and useful Improvements inWear Plates, of which the following is a specification.

My present invention has reference to i Wear plates for telegraph,telephone poles and the like, and has for its primary object to preventwear and consequent weakening of the poles incident to the strain of theguy wires and line wires that support the cables.

A further objectis to produce a Wear plate for this purpose comprising asec tional metal annulus adapted to surround the pole at an appropriatepoint, means being provided for adjustably securing the sections of theannulus on the pole whereby the same may accommodate itself to poles ofvarying cross sectional diameters, said means also securing on theannulus plates carrying hooks to which the guy Wires are connected.

To the attainment of the foregoing and other objects which will presentthemselves as the nature of the invention is better understood,reference is to be had to the drawings which accompany and which formpart of this application.

In the drawings Figure 1 is a side elevation of a pole showing the wearplate secured therearound.

Figure 2 is a sectional view approximately on the line 2-2 of Figure 1.

Figure 3 is a sectional view on the line 3-3 of Figure 1.

Figure 4 is a sectional View approximately on the line H of Figure 2.

Figure 5 is a view looking toward the inner face of one of the annulussections.

Figure 6 is a perspective view of one of the lip carrying plates.

Referring now to the drawings in detail, 7

the numeral 1 designates a telegraph pole or the like designed tosupport thereon a line wire or cable and to be braced by guy wires.

In carrying out my invention I produce two metal plates each of asimilar size and construction. The plates 2 and 3 respectively are bentor rounded upon themselves, each plate. when so arranged being greaterthan a semi-circle and the ends of the plates are disposed in lappingrelation to produce an annulus.

Before the annulus is arranged around the pole 1, I bore an openingthrough the pole, and pass through said opening a headless bolt t. Thesides of the post through which the bolt 4 passes are notched to providesquare pockets for nuts 5, and through these nuts the bolt 4 is screwed.The bolt 4 passes through one of a plurality of spaced openings 6adjacent one end of both the sections 2 and 3 of the annulus and throughelongated openings 7 disposed longitudinally adjacent the opposite endsof the said sections 2 and 3. Each section 2 and 3 has one of its endsprovided with ribs 8 which afford a biting engagement in the post or atighter frictional engagement between the respective sections 2 and 3.Each of the sections 2 and 3 adjacent their lower ends have elongatedslots 9 disposed opposite the slots 7, and a series of openings 10disposed in a line with the openings 6.

In addition to the ribs 8 the outer ends of the sections 2 and 3 may beprovided with additional ribs for frictional engagement with a. plate 11through which the bolt 1- passes. There is screwed on the bolt 4 nuts 12which, of course, frictionally contact with the plate 11. Each plate 11,adjacent to its lower end has riveted or otherwise secured thereto thebody portion 13 of a plate which terminates in an upwardly directed lip14. The lip 14 may, of course, be integrally formed on the plate 11, andpassing through the lip carrying plates 11 and through aligning openings9 and 10 in the respective sect-ions 2 and 3 there are the shanks ofheaded lag screws 15. If desired, the sides of the post 1, in a linewith the lag screws may be and preferably are provided with squaredrecesses forming pockets for bolts 16 through which the lag screws arethreaded, and also, if desired,suitable locking means may be providedfor holding the outer nuts on the headless bolts 4 The guy wires aredesigned to be arranged on the lips of the plates and are an gularlydirected therefrom to suit-able "supports. The guy wires are preferablyprovided with the usual adjusting means, and from the foregoingdescription, when taken in connection with the drawings it will beseenthait I have presented a wear plate for wire carrying poles aroundwhichthe cable I wvires but reinforces and strengthens the pole. \VhileI have herein set forth a satis factory embodiment of thelIYlPIOVBDlGlld; as it now appears to me, it is of course, to beunderstood that I am entitled to such changes and modificationstherefrom as tall within the scope of what I claim.

Having described the invention, 1 claim l. The combination with a polehaving a headless bolt passing transversely there through, nuts on thebolt pocketed in the sides of the pole, and additional nuts below thefirst mentioned nuts also pocketed in the sides of the pole; of a wearplate comprising an annulus including two companion sections havingtheir adjacent ends overlapped and ribs at said overlapping ends saidlapping ends being provided with upper and lower slots and openingsrespectively the upper slots and openings receiving therethrough theends of the bolt, nuts screwed on said bolt, and lag screws passingthrough the lower slots and openings through the second mentioned nutsand entering the pole.

2. The combination with a pole having a headless bolt passingtransversely therethrough, nuts on the bolt pocketed in the sides of thepole, and additional nuts be low the first mentioned nuts also pocketedin the sides of the pole; oi? a wear plate comprising; an annulusincluding two companion sections having their adjacent ends overlappedand ribs at said overlapping ends, said lapping ends being provided withupper and lower slots and openings respectively, the upper slots andopenings receiving therethrough the ends of the bolt, nuts screwed onsaid bolt, and lag screws passing through the other slots and openings,through the second mentioned nuts and entering the pole, and plateshaving lipped lower ends connected to the war plate by said bolts andscrews.

In testimony whereof I afiix my signature.

SIDNEY B. CAMPBELL.
